( Figs 19-21 )

Examined material: Holotype ♂: NE Nepal, Jubing , 1300 m, I. Zhou 9.VII.2016 ( cB).

Description: Length of body 4 mm; from anterior margin of head to posterior margin of elytra: 2 mm. Body very dark reddish brown, with light brown antennae and legs. Head sub-rectangular, slightly narrow anteriad, with sub-rectilinear sides and rounded posterior angles. Eyes small and not protruding. Surface of head with traces of transverse micro-striation and fine, sparse punctation. Pronotum sub-rectangular, longer and a little narrower than head, with sub-rectilinear and sub-parallel sides, oblique anterior margins and largely rounded anterior angles. Surface with dorsal series of 7-8 fine punctures and oblique lateral series of 5-6 punctures. Elytra sub-rectangular, not dilated posteriad, with sub-parallel and sub-rectilinear sides, slightly longer and wider than pronotum, with conspicuous humeral angles. Surface with some series of very fine and scattered punctures. Abdomen with feebly traces of fine, transverse micro-striation and fine punctation on the sides.

Posterior margin of the sixth visible tergite rounded; posterior margin of the sixth visible sternite with median emargination. Tergite and sternite of the male genital segment as in Figs 19-20 . Aedeagus ( Fig. 21 ) 0.77 mm long, ovoid, with acute distal lobe and very short and narrow parameres; inner sac looks like a compact mass, in fact composed of two sets of large spines located very close together.

Etymology: The specific epithet refers to the type locality, as a noun in apposition.

Distribution: The species is known only from the type locality.

Remarks: Based on the external characters this species is closely related to the gardneri -group (for details see BORDONI, 2002).
